Swollen lymph nodes, extreme fatigue

I have been dealing with swollen lymph nodes for a few months now. They first started under my left armpit and went away within about two weeks or so. I didn't think much of it until the pain and swelling came back about two months later. I decided to see my doctor and she said my lymph nodes in my left armpit were swollen in a few spots and swollen stacked on top of each other. They took blood and did a chest x-ray to make sure there weren't more swollen that they couldn't see. Blood work came back normal and so did x-ray. It has been about three months since the swelling in my left armpit went away and I woke up with swollen lymph nodes in my neck. The swelling went away in my neck after a few days but then my right armpit was swollen with lumps. That lasted a couple days and now my left is swollen with lumps. I have been experiencing a few night sweats, extreme fatigue, dizziness and knee joint pain with this last stretch of swollen lymph nodes. I have an appointment on Monday to see my doctor but I am curious to see if anyone else has experienced something similar or could shed some light on my situation for me. Thank you for your time.
